Researchers Move Closer to Completely Optical Artificial Neural Network

Researchers have shown a neural network can be trained using an optical circuit (blue rectangle in the illustration). In the full network there would be several of these linked together. The laser inputs (green) encode information that is carried through the chip by optical waveguides (black). The chip performs operations crucial to the artificial neural network using tunable beam splitters, which are represented by the curved sections in the waveguides. These sections couple two adjacent waveguides together and are tuned by adjusting the settings of optical phase shifters (red and blue glowing objects), which act like 'knobs' that can be adjusted during training to perform a given task.

New Method Maps Contact Points Between Replicated DNA Molecules

News

Breaks in our DNA, which can occur spontaneously or result from irradiation or chemical insults, can lead to severe problems since they foster mutations and can ultimately lead to cancer. One of the main DNA repair pathways involves copying the missing information on the damaged DNA from the replicated sister chromatid. For this to occur, the two DNA molecules of sister chromatids need to come close together at the exact same genomic position. The team around Daniel Gerlich developed a method that solves this problem.
